  <!-- Overview
  ================================================== -->
  <div class="bs-docs-section">
    <div class="page-header">
      <h1 id="js-overview">Overview</h1>
    </div>

    <h3 id="js-individual-compiled">Individual or compiled</h3>
    <p>Plugins can be included individually (using Bootstrap's individual <code>*.js</code> files), or all at once (using <code>bootstrap.js</code> or the minified <code>bootstrap.min.js</code>).</p>

    <div class="bs-callout bs-callout-danger">
      <h4>Do not attempt to include both.</h4>
      <p>Both <code>bootstrap.js</code> and <code>bootstrap.min.js</code> contain all plugins in a single file.</p>
    </div>

    <div class="bs-callout bs-callout-danger">
      <h4>Plugin dependencies</h4>
      <p>Some plugins and CSS components depend on other plugins. If you include plugins individually, make sure to check for these dependencies in the docs. Also note that all plugins depend on jQuery (this means jQuery must be included <strong>before</strong> the plugin files). <a href="{{ site.repo }}/blob/v{{ site.current_version }}/bower.json">Consult our <code>bower.json</code></a> to see which versions of jQuery are supported.</p>
    </div>

    <h3 id="js-data-attrs">Data attributes</h3>
    <p>You can use all Bootstrap plugins purely through the markup API without writing a single line of JavaScript. This is Bootstrap's first-class API and should be your first consideration when using a plugin.</p>

    <p>That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the document namespaced with <code>data-api</code>. This looks like this:</p>
{% highlight js %}
$(document).off('.data-api')
{% endhighlight %}

    <p>Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:</p>
{% highlight js %}
$(document).off('.alert.data-api')
{% endhighlight %}

    <h3 id="js-programmatic-api">Programmatic API</h3>
    <p>We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.</p>
{% highlight js %}
$('.btn.danger').button('toggle').addClass('fat')
{% endhighlight %}

    <p>All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):</p>
{% highlight js %}
$('#myModal').modal()                      // initialized with defaults
$('#myModal').modal({ keyboard: false })   // initialized with no keyboard
$('#myModal').modal('show')                // initializes and invokes show immediately
{% endhighlight %}

    <p>Each plugin also exposes its raw constructor on a <code>Constructor</code> property: <code>$.fn.popover.Constructor</code>. If you'd like to get a particular plugin instance, retrieve it directly from an element: <code>$('[rel=popover]').data('popover')</code>.</p>

    <h3 id="js-noconflict">No conflict</h3>
    <p>Sometimes it is necessary to use Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions can occasionally occur. If this happens, you may call <code>.noConflict</code> on the plugin you wish to revert the value of.</p>
{% highlight js %}
var bootstrapButton = $.fn.button.noConflict() // return $.fn.button to previously assigned value
$.fn.bootstrapBtn = bootstrapButton            // give $().bootstrapBtn the Bootstrap functionality
{% endhighlight %}

    <h3 id="js-events">Events</h3>
    <p>Bootstrap provides custom events for most plugin's unique actions. Generally, these come in an infinitive and past participle form - where the infinitive (ex. <code>show</code>) is triggered at the start of an event, and its past participle form (ex. <code>shown</code>) is trigger on the completion of an action.</p>
    <p>As of 3.0.0, all Bootstrap events are namespaced.</p>
    <p>All infinitive events provide <code>preventDefault</code> functionality. This provides the ability to stop the execution of an action before it starts.</p>
{% highlight js %}
$('#myModal').on('show.bs.modal', function (e) {
  if (!data) return e.preventDefault() // stops modal from being shown
})
{% endhighlight %}

    <div class="bs-callout bs-callout-warning" id="callout-third-party-libs">
      <h4>Third-party libraries</h4>
      <p><strong>Bootstrap does not officially support third-party JavaScript libraries</strong> like Prototype or jQuery UI. Despite <code>.noConflict</code> and namespaced events, there may be compatibility problems that you need to fix on your own.</p>
    </div>
  </div>



  <!-- Transitions
  ================================================== -->
  <div class="bs-docs-section">
    <div class="page-header">
      <h1 id="transitions">Transitions <small>transition.js</small></h1>
    </div>
    <h3>About transitions</h3>
    <p>For simple transition effects, include <code>transition.js</code> once alongside the other JS files. If you're using the compiled (or minified) <code>bootstrap.js</code>, there is no need to include this&mdash;it's already there.</p>
    <h3>What's inside</h3>
    <p>Transition.js is a basic helper for <code>transitionEnd</code> events as well as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to catch hanging transitions.</p>
  </div>



  <!-- Modal
  ================================================== -->
  <div class="bs-docs-section">
    <div class="page-header">
      <h1 id="modals">Modals <small>modal.js</small></h1>
    </div>

    <h2 id="modals-examples">Examples</h2>
    <p>Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.</p>

    <div class="bs-callout bs-callout-warning" id="callout-stacked-modals">
      <h4>Overlapping modals not supported</h4>
      <p>Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.</p>
    </div>
    <div class="bs-callout bs-callout-warning">
      <h4>Mobile device caveats</h4>
      <p>There are some caveats regarding using modals on mobile devices. <a href="../getting-started/#support-fixed-position-keyboards">See our browser support docs</a> for details.</p>

    <h2 id="modals-usage">Usage</h2>
    <p>The modal plugin toggles your hidden content on demand, via data attributes or JavaScript. It also adds <code>.modal-open</code> to the <code>&lt;body&gt;</code> to override default scrolling behavior and generates a <code>.modal-backdrop</code> to provide a click area for dismissing shown modals when clicking outside the modal.</p>

    <h3>Via data attributes</h3>
    <p>Activate a modal without writing JavaScript. Set <code>data-toggle="modal"</code> on a controller element, like a button, along with a <code>data-target="#foo"</code> or <code>href="#foo"</code> to target a specific modal to toggle.</p>
{% highlight html %}
<button type="button" data-toggle="modal" data-target="#myModal">Launch modal</button>
{% endhighlight %}

    <h3>Via JavaScript</h3>
    <p>Call a modal with id <code>myModal</code> with a single line of JavaScript:</p>
    {% highlight js %}$('#myModal').modal(options){% endhighlight %}

    <h3>Options</h3>
    <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-backdrop=""</code>.</p>

    <h3>Methods</h3>

    <h4>.modal(options)</h4>
    <p>Activates your content as a modal. Accepts an optional options <code>object</code>.</p>
{% highlight js %}
$('#myModal').modal({
  keyboard: false

{% endhighlight %}

    <h4>.modal('toggle')</h4>
    <p>Manually toggles a modal. <strong>Returns to the caller before the modal has actually been shown or hidden</strong> (i.e. before the <code>shown.bs.modal</code> or <code>hidden.bs.modal</code> event occurs).</p>
    {% highlight js %}$('#myModal').modal('toggle'){% endhighlight %}

    <h4>.modal('show')</h4>
    <p>Manually opens a modal. <strong>Returns to the caller before the modal has actually been shown</strong> (i.e. before the <code>shown.bs.modal</code> event occurs).</p>
    {% highlight js %}$('#myModal').modal('show'){% endhighlight %}

    <h4>.modal('hide')</h4>
    <p>Manually hides a modal. <strong>Returns to the caller before the modal has actually been hidden</strong> (i.e. before the <code>hidden.bs.modal</code> event occurs).</p>
    {% highlight js %}$('#myModal').modal('hide'){% endhighlight %}

    <h2 id="dropdowns-usage">Usage</h2>
    <p>Via data attributes or JavaScript, the dropdown plugin toggles hidden content (dropdown menus) by toggling the <code>.open</code> class on the parent list item. When opened, the plugin also adds <code>.dropdown-backdrop</code> as a click area for closing dropdown menus when clicking outside the menu. Note: The <code>data-toggle=dropdown</code> attribute is relied on for closing dropdown menus at an application level, so it's a good idea to always use it.</p>

    <h3>Via data attributes</h3>
    <p>Add <code>data-toggle="dropdown"</code> to a link or button to toggle a dropdown.</p>
{% highlight html %}
<div class="dropdown">
  <a data-toggle="dropdown" href="#">Dropdown trigger</a>
  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">
    ...
  </ul>
</div>
{% endhighlight %}
          <p>To keep URLs intact, use the <code>data-target</code> attribute instead of <code>href="#"</code>.</p>
{% highlight html %}
<div class="dropdown">
  <a id="dLabel" role="button" data-toggle="dropdown" data-target="#" href="/page.html">
    Dropdown <span class="caret"></span>
  </a>


  <ul class="dropdown-menu" role="menu" aria-labelledby="dLabel">

  </ul>
</div>
{% endhighlight %}

    <h3>Via JavaScript</h3>
    <p>Call the dropdowns via JavaScript:</p>
{% highlight js %}
$('.dropdown-toggle').dropdown()
{% endhighlight %}

    <h3>Options</h3>
    <p><em>None</em></p>

    <h3>Methods</h3>
    <h4>$().dropdown('toggle')</h4>

    <h2 id="scrollspy-usage">Usage</h2>

    <h3>Via data attributes</h3>
    <p>To easily add scrollspy behavior to your topbar navigation, add <code>data-spy="scroll"</code> to the element you want to spy on (most typically this would be the <code>&lt;body&gt;</code>). Then add the <code>data-target</code> attribute with the ID or class of the parent element of any Bootstrap <code>.nav</code> component.</p>
{% highlight html %}
<body data-spy="scroll" data-target=".navbar-example">
  ...
  <div class="navbar-example">
    <ul class="nav nav-tabs">
      ...
    </ul>
  </div>
  ...
</body>
{% endhighlight %}

    <h3>Via JavaScript</h3>
    <p>Call the scrollspy via JavaScript:</p>
{% highlight js %}
$('body').scrollspy({ target: '.navbar-example' })
{% endhighlight %}

    <div class="bs-callout bs-callout-danger">
      <h4>Resolvable ID targets required</h4>
      <p>Navbar links must have resolvable id targets. For example, a <code>&lt;a href="#home"&gt;home&lt;/a&gt;</code> must correspond to something in the DOM like <code>&lt;div id="home"&gt;&lt;/div&gt;</code>.</p>
    </div>

    <h3>Methods</h3>
    <h4>.scrollspy('refresh')</h4>
    <p>When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:</p>
{% highlight js %}
$('[data-spy="scroll"]').each(function () {
  var $spy = $(this).scrollspy('refresh')
})
{% endhighlight %}


    <h3>Options</h3>
    <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-offset=""</code>.</p>

    </div>
    <div class="bs-callout bs-callout-info">
      <h4>Tooltips in button groups and input groups require special setting</h4>
      <p>When using tooltips on elements within a <code>.btn-group</code> or an <code>.input-group</code>, you'll have to specify the option <code>container: 'body'</code> (documented below) to avoid unwanted side effects (such as the element growing wider and/or losing its rounded corners when the tooltip is triggered).</p>

    <div class="bs-callout bs-callout-info">
      <h4>Tooltips on disabled elements require wrapper elements</h4>
      <p>To add a tooltip to a <code>disabled</code> or <code>.disabled</code> element, put the element inside of a <code>&lt;div&gt;</code> and apply the tooltip to that <code>&lt;div&gt;</code> instead.</p>
    </div>

    <h2 id="tooltips-usage">Usage</h2>
    <p>The tooltip plugin generates content and markup on demand, and by default places tooltips after their trigger element.</p>
    <p>Trigger the tooltip via JavaScript:</p>
{% highlight js %}
$('#example').tooltip(options)
{% endhighlight %}

    <h3>Markup</h3>
    <p>The required markup for a tooltip is only a <code>data</code> attribute and <code>title</code> on the HTML element you wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to <code>top</code> by the plugin).</p>
    <div class="bs-callout bs-callout-warning">
      <h4>Multiple-line links</h4>
      <p>Sometimes you want to add a tooltip to a hyperlink that wraps multiple lines. The default behavior of the tooltip plugin is to center it horizontally and vertically. Add <code>white-space: nowrap;</code> to your anchors to avoid this.</p>
    </div>

    <p>Data attributes are integral to the button plugin. Check out the example code below for the various markup types.</p>

    <h3>Options</h3>
    <p><em>None</em></p>

    <h3>Methods</h3>

    <h4>$().button('toggle')</h4>

    <p>You can also use the plugin without the accordion markup. Make a button toggle the expanding and collapsing of another element.</p>
{% highlight html %}
<button type="button" class="btn btn-danger" data-toggle="collapse" data-target="#demo">
  simple collapsible
</button>

<div id="demo" class="collapse in">...</div>
{% endhighlight %}


    <h2 id="collapse-usage">Usage</h2>
    <p>The collapse plugin utilizes a few classes to handle the heavy lifting:</p>
    <ul>
      <li><code>.collapse</code> hides the content</li>
      <li><code>.collapse.in</code> shows the content</li>
      <li><code>.collapsing</code> is added when the transition starts, and removed when it finishes</li>
    </ul>
    <p>These classes can be found in <code>component-animations.less</code>.</p>

    <h3>Via data attributes</h3>
    <p>Just add <code>data-toggle="collapse"</code> and a <code>data-target</code> to element to automatically assign control of a collapsible element. The <code>data-target</code> attribute accepts a CSS selector to apply the collapse to. Be sure to add the class <code>collapse</code> to the collapsible element. If you'd like it to default open, add the additional class <code>in</code>.</p>
    <p>To add accordion-like group management to a collapsible control, add the data attribute <code>data-parent="#selector"</code>. Refer to the demo to see this in action.</p>

    <h3>Via JavaScript</h3>
    <p>Enable manually with:</p>
{% highlight js %}
$('.collapse').collapse()
{% endhighlight %}

    <h3>Options</h3>
    <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-parent=""</code>.</p>

  <h4>Transition animations not supported in Internet Explorer 8 &amp; 9</h4>
  <p>Bootstrap exclusively uses CSS3 for its animations, but Internet Explorer 8 &amp; 9 don't support the necessary CSS properties. Thus, there are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.</p>

  <h4>Accessibility issue</h4>
  <p>The carousel component is generally not compliant with accessibility standards. If you need to be compliant, please consider other options for presenting your content.</p>
</div>

    <h2 id="carousel-usage">Usage</h2>

    <h3>Via data attributes</h3>
    <p>Use data attributes to easily control the position of the carousel. <code>data-slide</code> accepts the keywords <code>prev</code> or <code>next</code>, which alters the slide position relative to its current position. Alternatively, use <code>data-slide-to</code> to pass a raw slide index to the carousel <code>data-slide-to="2"</code>, which shifts the slide position to a particular index beginning with <code>0</code>.</p>
    <p>The <code>data-ride="carousel"</code> attribute is used to mark a carousel as animating starting at page load.</p>

    <h3>Via JavaScript</h3>
    <p>Call carousel manually with:</p>
{% highlight js %}
$('.carousel').carousel()
{% endhighlight %}

    <h3>Options</h3>
    <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-interval=""</code>.</p>
    <div class="table-responsive">
      <table class="table table-bordered table-striped">

    <h4>.carousel('cycle')</h4>
    <p>Cycles through the carousel items from left to right.</p>

    <h4>.carousel('pause')</h4>
    <p>Stops the carousel from cycling through items.</p>


    <h4>.carousel(number)</h4>
    <p>Cycles the carousel to a particular frame (0 based, similar to an array).</p>

    <h4>.carousel('prev')</h4>
    <p>Cycles to the previous item.</p>

    <h4>.carousel('next')</h4>
    <p>Cycles to the next item.</p>

    <h3>Events</h3>
    <p>Bootstrap's carousel class exposes two events for hooking into carousel functionality.</p>

  <!-- Affix
  ================================================== -->
  <div class="bs-docs-section">
    <div class="page-header">
      <h1 id="affix">Affix <small>affix.js</small></h1>
    </div>

    <h2 id="affix-examples">Example</h2>
    <p>The subnavigation on the left is a live demo of the affix plugin.</p>

    <hr class="bs-docs-separator">

    <h2 id="affix-usage">Usage</h2>
    <p>Use the affix plugin via data attributes or manually with your own JavaScript. <strong>In both situations, you must provide CSS for the positioning of your content.</strong></p>

    <h3>Positioning via CSS</h3>
    <p>The affix plugin toggles between three classes, each representing a particular state: <code>.affix</code>, <code>.affix-top</code>, and <code>.affix-bottom</code>. You must provide the styles for these classes yourself (independent of this plugin) to handle the actual positions.</p>
    <p>Here's how the affix plugin works:</p>
    <ol>
      <li>To start, the plugin adds <code>.affix-top</code> to indicate the element is in its top-most position. At this point no CSS positioning is required.</li>
      <li>Scrolling past the element you want affixed should trigger the actual affixing. This is where <code>.affix</code> replaces <code>.affix-top</code> and sets <code>position: fixed;</code> (provided by Bootstrap's code CSS).</li>
      <li>If a bottom offset is defined, scrolling past that should replace <code>.affix</code> with <code>.affix-bottom</code>. Since offsets are optional, setting one requires you to set the appropriate CSS. In this case, add <code>position: absolute;</code> when necessary. The plugin uses the data attribute or JavaScript option to determine where to position the element from there.</li>
    </ol>
    <p>Follow the above steps to set your CSS for either of the usage options below.</p>

    <h3>Via data attributes</h3>
    <p>To easily add affix behavior to any element, just add <code>data-spy="affix"</code> to the element you want to spy on. Use offsets to define when to toggle the pinning of an element.</p>

{% highlight html %}
<div data-spy="affix" data-offset-top="60" data-offset-bottom="200">
  ...
</div>
{% endhighlight %}

    <h3>Via JavaScript</h3>
    <p>Call the affix plugin via JavaScript:</p>
{% highlight js %}
  $('#myAffix').affix({
    offset: {
      top: 100
    , bottom: function () {
        return (this.bottom = $('.bs-footer').outerHeight(true))
      }
    }
  })
{% endhighlight %}


    <h3>Options</h3>
    <p>Options can be passed via data attributes or JavaScript. For data attributes, append the option name to <code>data-</code>, as in <code>data-offset-top="200"</code>.</p>

    <div class="table-responsive">
      <table class="table table-bordered table-striped">
        <thead>
         <tr>
           <th style="width: 100px;">Name</th>
           <th style="width: 100px;">type</th>
           <th style="width: 50px;">default</th>
           <th>description</th>
         </tr>
        </thead>
        <tbody>
         <tr>
           <td>offset</td>
           <td>number | function | object</td>
           <td>10</td>
           <td>Pixels to offset from screen when calculating position of scroll. If a single number is provided, the offset will be applied in both top and bottom directions. To provide a unique, bottom and top offset just provide an object <code>offset: { top: 10 }</code> or <code>offset: { top: 10, bottom: 5 }</code>. Use a function when you need to dynamically calculate an offset.</td>
         </tr>
        </tbody>
      </table>
    </div><!-- /.table-responsive -->


    <h3>Events</h3>
    <p>Bootstrap's affix class exposes a few events for hooking into affix functionality.</p>

      <table class="table table-bordered table-striped">
